    Hello All,

    Do anyone have experience on Indoor Coverage Design, especially on Distributed Ant. existing together with Fiber Repeater ?

    My question is :
    > While installing FB(Fiber Repeater) and DAS(trans. RF signal via coaxial cable), the FB feeds back noise to BTS and degrades performance of DAS, especially Drop Calls.
    > While tuning UL FB gain down to the same level of DAS feeding to BTS, the UL signal level of FB is too low to proceed successful handovers. Many handovers failures caused by UL strength appear.
    > Do anyone know how to evaluate the proper setting in this situation ? Or can anyone tell me the approach to get the most suitable setting ?

    Thanks & BR,

    TWeng
